River Potholes: Modern And Ancient, Robert F. Diffendal Jr.

Robert F. Diffendal, Jr., Publications

A river pothole is a cylindrical, bowl-shaped, or irregular hollow that is usually deeper than wide. It is formed in the rocky bed of a stream by either the grinding action of sediment whirled around by stream eddies or the force of fast flowing water. Potholes usually have spirally grooved surfaces. Their widths and depths range from a few inches to many feet. Potholes on the floor of the Susquehanna River near Columbia, Pennsylvania, for example, are large enough to hold objects the size of a small car.

Potholes generally are formed in fairly homogeneous rock by streams that at …

Nutrient Cycling In Bordenstake Bay Sediments: A Backbarrier Lagoon, Mark J. Herrenkohl

OES Theses and Dissertations

Six sets of sediment cores were collected over a one year period (June 1986 to July 1987) to examine nutrient cycling in Bordenstake Bay, a back barrier lagoon on Virginia's Eastern Shore Peninsula. The sampling times were chosen to examine any seasonal effects (e.g., temperature changes) which may affect the rates of metabolism in these sediments.

The sedimentation rate in Bordenstake Bay is 0.76 ± 0.21 cm/yr, leading to the annual deposition of 7. 05 moles of carbon, 0.46 moles of nitrogen, and 0.15 moles of phosphorus, per square meter of the sediment surface. The remineralization of organic matter in …

An Inventory And Condition Survey Of Rangelands In The Ashburton River Catchment, Western Australia, A A. Mitchell, A L. Payne, W F. Holman

Technical Bulletins

The inventory and condition survey of rangelands in the Ashburton River catchment, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 1976 and 1978, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The area surveyed …

A Monograph Of The Genus Polyphylla Harris In America North Of Mexico (Coleoptera: Scarabaeidae: Melolonthinae), Ronald M. Young

Bulletin of the University of Nebraska State Museum (1924–2023)

The North American species of the genus Polyphylla Harris, 1841, are defined and revised for the first time since Fall (1928). All name bearing types were examined except those of P. oklahomensis Hatch and P. subvittata LeConte (synonyms of P. hammondl), which are lost. A lectotype is designated for P. gracilis Horn, and neotypes for P. decemlineata (Say), P. occidentalis (L.), and P. variolosa (Hentz). New synonyms of P. decemlineata are P. comstockiana von Bloeker, P. matrona Casey, and P. potsiana Casey. New synonyms of P. crinita …
